Abstract

본 발명은 촉매, 기포 안정제 및 기포 개방제의 존재하에서 발포제로서 트리클로로플루오로메탄 대신에 1,1-디크로로-1-플루오로에탄 또는 메틸렌클로라이드 같은 휘발성 발포제 또는 이러한 휘발성 발포제와 물과의 혼합물을 사용하여 폴리올과 모노올(예을들면, 디에틸렌글리콜모노메틸에테르) 함유 폴리메틸렌 폴리페닐폴리이소시아네이트 초기 중합체를 반응시키는 것으로 이루어진 연속 기포 경질 폴리우레탄 포옴의 제조 방법에 관한 것이다. 제조된 연속 기포 경질 폴리우레탄 포옴은 기포 크기가 약 200-250 마이크론이고, 진공 단열재의 중심물질로 사용하기에 적합하다, 상기 포옴을 쉽게 도달할 수 있는 진공도 0.1-0.0 mmHg하의 용기내에 봉입시켜 단열 성능이 우수한 진공 단열재를 제공할 수 있다.The present invention relates to a volatile blowing agent such as 1,1-dichloro-1-fluoroethane or methylene chloride or water with a volatile blowing agent in place of trichlorofluoromethane as blowing agent in the presence of a catalyst, bubble stabilizer and bubble opener. A mixture of polyols and monools (eg, diethylene glycol monomethyl ether) containing polymethylene polyphenylpolyisocyanate initial polymers is used to prepare a continuous bubble rigid polyurethane foam. The prepared continuous bubble rigid polyurethane foam has a bubble size of about 200-250 microns and is suitable for use as a core material for vacuum insulators. The foams are enclosed in a container under a vacuum degree of 0.1-0.0 mmHg which is easily reached and insulated. A vacuum insulator having excellent performance can be provided.
